- Description
The RASA11 telescope requires 72.8mm of back focus. When using a full frame camera you want to have the most clearance available to prevent vignetting.
The Baader UFC system provides the ridged mounting required to support a full frame camera and to achieve extremely accurate back focus. We have packaged up the required parts into one convenient part number.
The kit includes:
2459126 RASA adapter
2459145 15-20mm vari ring
2459142 15mm ring
2459110 filter base
2459112 2” (48mm mounted) filter slide
2459117 M54 adapter
All of the parts, including the camera with the angle adjustment ring is 70.5mm. The vari adapter that I also included will let you get exactly 72.8mm. There is usually a .5mm tolerance.
